Description Scott Dodson 2017-05-18 21:15:51 UTC
+++ This bug was initially created as a clone of Bug #1452235 +++

Description of problem:

tuned-profiles-atomic-openshift-node-3.5.*.rpm(s) contain an outdated atomic-openshift-node-host profile.

Version-Release number of selected component (if applicable):
tuned-profiles-atomic-openshift-node-3.5.5.17-1.git.0.28f23d1.el7.x86_64.rpm and lower.

$ oc version
oc v3.5.5.10
kubernetes v1.5.2+43a9be4
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://192.1.0.133:8443
openshift v3.5.5.10
kubernetes v1.5.2+43a9be4

How reproducible:
Always.

Steps to Reproduce:

$ rpm -qf /usr/lib/tuned/atomic-openshift-node-guest/tuned.conf
tuned-profiles-atomic-openshift-node-3.5.5.5-1.git.0.f2e87ab.el7.x86_64

$ grep gc_ /usr/lib/tuned/atomic-openshift-node-host/tuned.conf
$ grep gc_ /usr/lib/tuned/atomic-openshift-node-guest/tuned.conf
net.ipv4.neigh.default.gc_thresh1=8192
net.ipv4.neigh.default.gc_thresh2=32768
net.ipv4.neigh.default.gc_thresh3=65536

$ curl -Ls https://raw.githubusercontent.com/openshift/origin/master/contrib/tuned/origin-node-host/tuned.conf | grep gc_
net.ipv4.neigh.default.gc_thresh1=8192
net.ipv4.neigh.default.gc_thresh2=32768
net.ipv4.neigh.default.gc_thresh3=65536

Actual results:


Expected results:

$ grep gc_ /usr/lib/tuned/atomic-openshift-node-host/tuned.conf
net.ipv4.neigh.default.gc_thresh1=8192
net.ipv4.neigh.default.gc_thresh2=32768
net.ipv4.neigh.default.gc_thresh3=65536

Additional info:
https://bugzilla.redhat.com/show_bug.cgi?id=1425388

Checked tuned-profiles-atomic-openshift-node-3.6.74-1.git.0.e6d1637.el7.x86_64.rpm and it is fixed there, so it only looks like 3.5.x is affected?
